Is it possible for a fresh water tank to drain itself into a grey water tank inside the belly ?
I could be wrong, but I thought my grey water tank was empty a week ago but today it had 6 or 8 gallons in it.
My fresh water tank seems to be empty and I thought it had a few gallons left but not sure.
Nothing is leaking or running inside camper, pump is off and has been off for a couple weeks.
Does anyone know of a picture or drawing showing approx how the grey, black and fresh water tanks are made on a 2000 excella ?
